Paginate countries' page

[oesukam]

Page: https://covid-19info.cd/countries

Problem:

• Listing all countries doesn't give a good user experience even if there is a search bar

Recommendation:

• It will be better to include pagination and filters per continent and regions if possible
• Also having a possibility to sort countries by differents information such as the most affected, having active cases, recovered and so on

@oesukam we use the jhu api for countries, you can reopen this issue, on the repository https://github.com/devscast/covid19-client
it's the frontend that has to take care of this.
